Display of colours

Hi,

I'm currently producing a 3d view of a room.  I'm applying ordinary colours to
the walls, ceilings etc.  When I do the radiosity solution and look at the scene
in the preview pane everything looks great.  But when I do a full render the
colours don't display correctly.  Two things happen in the full render display,
(i) the colours on the walls/ceilings have dark blotches all through them and
some complete walls are not coloured at all, and (ii) if I close the rendered
image and just render again without changing any settings, the image differs in
regard to which walls are rendered properly.  In other words, one wall could
come out perfectly in the rendered image with other walls being blotchy or no
colour, and if I render again without changing anything, this same wall could
this time be blotchy and have no colour but the other would be fine.  Any advice
would be much appreciated.  Thank

My first guess would be that you've got two copies of the problematic 
objects in the same place. But I could be wrong.
